That works for me, thanks!

If that was the case, wouldn't @3$3 sum up to 3+0=3? Now it shows 7.

I suspect @2$3 was 4 when you evaluated the formulas, hence the 7.
If you clear column c completely, what is the output of the evaluation then?
I get:
| a | b | c |
|---+----+---|
| a | 2 | 2 |
| b | 3 | 3 |
| c | -3 | 0 |
| d | 5 | 5 |

The same. And so now I can't reproduce my original problem... that's
good, I guess.

That works. Thanks!
Here's another thing I'm trying:
| a | b | c |
| | 7 | 210 |
|---+----+-----|
| a | 2 | 30 |
| b | 3 | 5 |
| c | -3 | 2 |
| d | 5 | 7 |
#+TBLFM: @2$2=vsum(@3$2..@6$2)::@2$3=vsum(@3$3..$LR3)
I want row 2 to contain sums for what's below. Is there a way to make
the LR-reference work here?

Evaluating the field formulas before the column formulas is in general a bad
idea. Results of the field formulas will always be overwritten by the column
formulas (if there is a conflict).
Here you need to evaluate the spreadsheet twice to yield the intended result (I
get a 5 in field @2$3). From info:org:Updating the table:

When recomputing a table, Org evaluates field formulas first.
Then it does the column formulas, but never overwrites a field
that was filled with a field formula.

Indeed, this is what is needed here.

I have a table like this one:
| a | b | c |
|---+----+---|
| a | 2 | 2 |
| b | 3 | 7 |
| c | -3 | 4 |
| d | 5 | 9 |
#+TBLFM: $3=$2+@-1::@2$3=$2
Now, I want the value in column c in every row to be the sum of column b so
far. I try to achieve this by writing a column formula for column $3 and a
cell formula for cell @2$3. Note that cell @3$3 is incorrect whereas all the
other are correct. I have tried different formulas and values, and it seems
like the incorrect cell is the sum of three cells instead of two as
intended. @2$2 wasn't supposed to be part of the sum. Am I doing something
incorrectly here?

A good solution is to use
$3=vsum(@-I$-1..$-1)
as proposed in this thread:
http://thread.gmane.org/gmane.emacs.orgmode/1940/focus=1941
Nevertheless:
If @2$3 is manually set to 2 in the table, then the formulas produce
the expected outcome. So, the problem seems to be the order of
execution. If column c is cleared and the formulas are executed, @2$3
is read to be 0 for the summation and is set to 2 only afterwards.
Swapping the order in the TBLFM line doesn't help.
Is the order something like field formulas after column formulas?
Any chance to influence that?
